Chemistry that reacts when you do.
Six live models for Paper 2. Balance equations, heat a reaction, add an indicator drop by drop and build a battery — the numbers update as you go.
6 live models 18 missions Auto-balancing equations
Chemistry Lab · live models
Mix, heat, titrate, measure.
Choose a model, move the sliders or type an equation, a name or a titration. Missions reward you for spotting the chemistry.

What you can explore
Mapped to the CAPS Grade 12 syllabus
Each experiment matches a topic in the NSC Physical Sciences exam, with the same equations and data-sheet values you use in the paper.
Reaction rates
Maxwell–Boltzmann curves, activation energy, catalysts and colliding particles.
Chemical change · Paper 2Chemical equilibrium
Disturb the Haber process and watch Le Chatelier's principle in real time.
Chemical change · Paper 2Acids & bases
Titration curves, pH, equivalence points and indicator colours.
Chemical change · Paper 2Electrochemistry
Build galvanic cells from the standard reduction table and read E°cell.

Questions
Frequently asked
Can the lab balance any chemical equation?
It balances any equation that has one correct set of whole-number coefficients, such as combustion and redox equations written with formulas, for example C3H8 + O2 -> CO2 + H2O.
Which data does it use?
Molar masses and standard reduction potentials match the values on the NSC Physical Sciences data sheets.
Does it name organic molecules?
Yes, for unbranched alkanes, alkenes, alcohols, aldehydes, ketones, carboxylic acids and chloroalkanes with up to ten carbon atoms.
Is it free?
Yes. All labs on Biemann EduHub are free for learners, parents and teachers.
